Support for control socket to interact with running vm

[balajiv113]

A control socket need to be implemented, using this external service can send events / actions like pause, resume to current running vm state

Describe the solution you'd like

• A control socket needs to be created only after vm is started (can refer pid creation)
• A go-routine / similar stuff for reading events via that control sock
• Handle event

Describe alternatives you've considered
This solution is similar to the one QEMU has. But we will improve incrementally. For now, events for pause and resume should be sufficient
